Specification of Letters Patent.

Patented Aug. 26,1913.

Application filed December 11, 1912. Serial No. 736,113.

To all whom it may concern Be it known that I, WILLIAM J. KAN'ro- MAA, acitizen of the United States, residing at Lanesville, in the county ofEssex, State of Massachusetts, have invented certain new and usefulImprovements in Anchors; and I do declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it pertains to make and use the same.

My invention relates to an improvement. in anchors for use with vesselsof all descriptions. It has for its object to provide means whereby thefiukes of the anchor can be readily disengaged from their hold on thebottom of the sea, or other body of water, when caught by somesub-marine obstruction or other entanglement and prevent the consequentloss of the anchor by its having to be abandoned. It also has for itsobject to provide an anchor which when in use will hold the same as anyordinary anchor but when it is desired to hoist or raise it the fiukeswill automatically free themselves and assume a position which will notimpede the hoisting or raising of the anchor. It further has for itsobject to provide an anchor which is simple, inexpensive and durable inconstruction and easy and effective in use.

The invention consists in the several features and construction,combination and arrangement of features as more fully hereinafterdescribed and claimed.

Referring to the drawings :-Figure 1 is a side view in elevation showingthe anchor in the position itassumes when ready for use. Fig. 2 a sideview in elevation showing the anchor in the position it assumes when theflukes are released and the anchor is ready to be hoisted or raised.Fig. 3 an edge view. Fig. 4 a detail view of the lower portion of theanchor broken away to show the operating mechanism of the fiukes. Fig. 5a detail sectional view of the upper portion of the shank, stock and baroperat ing lever.

In the drawings in which like numerals of reference denote like partsthroughout the several views, 1 represents the shank of the anchor madein two pieces 2 and 3 each provided at the upper end with a circularportion 4, having square holes 5 therethrough, and each provided at itslower end. with an enlarged portion 6 having bolt holes therethrough.The stock 7 of the anchor is provided with a squared middle portion 8which is inserted in the square holes 5 of shank and held securelytherein by split pins 9 which pass through the square portion of thestock. The enlarged portions 6 of the shank are held together by meansof bolts 10 and split pins. The two fiukes 11 of the anchor are pivotedbetween the en larged portions 6 of the shank by means of bolts 12, saidflukes each being provided with cogged sectors 13 on its inner end and afluke point 14 011 its outer end.

A bar 15 is operatively mounted between the two parts 2 and 3 of theanchor shank 1, between which it is designed to oscillate andreciprocate, and is provided on each edge of its lower portion withteeth 16 which mesh with the cogged sectors 13 of the flukes 11, whileits upper end 17 is provided with a hole 18.

A lever 19 is pivotally mounted on an enlarged rounded portion 20 of thestock and has a forked lower end 21 which is pivoted to the upper end 17of the bar 15 by means of a pin 22. The lever 19 is provided withlateral shoulders 23 which bear and ride 011 the circular portions 4 ofthe two parts 2 and 3 of the shank. The lever 19 tapers gradually fromthe shoulders 28 to its upper end 24 where it is provided with a pivotedlink 25.

The anchor chain is adapted to be attached to the link 25 of the lever19.

I do not desire to be understood as limiting myself to the specificdetails of construction and arrangement as herein described andillustrated, as it is manifest that variations and modifications may bemade in the features of construction and arrangement in the adaptationof the device to various conditions of use without departing from thespirit and scope of my invention and improvements. I therefore reservethe right to all such variations and modifications as properly fallwithin the scope of my invention and the terms of the following claims:

What I claim is 1. In an anchor, pivoted fiukes, an oscillatory andreciprocatory bar, means for operatively connecting said fiukes withsaid bar and means for operating said bar, substantially as described.

2. In an anchor, a two part shank, pivoted flukes, an oscillatory andreciprocatory bar between the parts of said shank, means operativelyconnecting said bar with said 3. In an anchor, a two part shank, flukespivoted between the two parts of the shank, an oscillatory andreciprocatory bar between the said two parts of the shank, meansoperatively connecting the bar with the flukes: and means for operatingthe bar, substanthe stock of the anchor and pivotally contially asdescribed.

4-. In an anchor, a two part shank, fiukes each provided with a toothedsector, a bar between the two parts of the shank and having teeth whichmesh with the toothed sectors of the flukes and means for operating thesaid bar, substantially as described.

5. In an anchor, a two part shank, flukes each provided with a toothedsector, a bar between the two parts of the shank and having teeth whichmesh with the toothed sectors of the flukes, a lever pivotally mountedon the stock of said anchor and pivotally connected to the said bar,substantially as described.

6. In an anchor, a two part shank, flukes pivoted between the two partsof the shank, a bar between the two parts of the shank operativelyconnected at one end to the flukes, a lever pivotally mounted on thestock of said anchor between the two parts of the shank and pivotallyconnected to the said bar and means for operating said bar,

substantially as described.

7. In an anchor, a two part shank, flukes pivoted between the two partsof the shank having toothed sectors, a bar pivoted between the two partsof said shank having teeth which mesh with the toothed sectors of thefiukes, a lever pivotally mounted on nected to said bar and means foroperating said bar, substantially as described.

8. In an anchor, a two part shank, each part having a circular upperportion, fiukes pivoted between the parts of said shank and havingtoothed sectors, a bar pivoted between the two parts of the shank andhaving teeth meshing with the toothed sectors of the flukes, a leverpivotally mounted on the stock of said anchor and pivotally connected tosaid bar, said lever provided with lateral shoulders which engage thecircular portions of the shanks and means for operating said bar,substantially as described.

In testimony whereof I aflix my signature in the presence of twowitnesses.
